“…The induction of this type of aberration may be owing to the disturbance in nucleic acid metabolism in the cell (Kaul 1972). Moreover, many investigators found that Cd and Pb are extremely toxic elements and they could reduce the mitotic activity and induced many types of chromosomal anomalies (Mukherji et al 1990, Gupta and Ghosh 1992, Abu Saidah 1995, AbdelAzeem and El-Nahas 1996. Table 1 also showed that GA 3 application greatly increased mitotic index, whereas the frequency of chromosomal aberrations clearly decreased.…”

SummaryThe influence of gibberellic acid, two heavy metals (cadmium and lead) and their interactions on mitotic activity and biochemical constituents of Vicia faba yielded seeds was studied. The results showed that different concentrations of cadmium (Cd) and lead (Pb) induced marked inhibition in the contents of soluble carbohydrate, proteins and ribonucleic acid. Heavy metals also induced marked increases of the total percentage of abnormalities. Moreover, different types of chromosomal aberrations were observed in response to heavy metals. On the contrary, gibberellic acid (GA 3 ) stimulated mitotic activity and biochemical constituents of the yielded seeds of Vicia faba. Gibberellic acid could be also counteracted the adverse effects of heavy metals on mitotic index and some metabolic mechanisms of broad bean plants. In addition, electrophoretic profiles of broad bean seeds proteins showed quantitative differences between major bands obtained in control and treated plants.

“…In certain concentrations, there was an increase in germination including shoot and root lengths and this might be due to heavy metal critical points for black gram. Most of the heavy metals can lead to reduce the mitotic activity and persuade many types of chromosomal abnormalities which in turn inhibit the growth and development 34,35 .…”

Vigna mungo generally called as black gram is a nutrient food crop which is widely used in Indian cuisine and also used in traditional ayurvedic medicine. By natural and anthropogenic activities, black gram growth is highly affecting by heavy metal pollution. Hence, it is necessary to conduct the experiments to know the effects of various heavy metals on growth of black gram in turn yield levels. In the current study, we aimed to study the in vitro effects of heavy metals such as chromium (Cr), cadmium (Cd), cobalt (Co) and lead (Pb) on germination of seeds and seedling morphology of black gram. The concentrations include 1, 10, 20, 50 and 100 ppm of respective heavy metal (Cr, Cd, Co and Pb) along with the two positive controls i.e. tap water (T.W) and distilled water (D.W) were used without any heavy metal for the preparation of media. Upon treatment, percentage of germination and both root and shoot lengths of black gram were significantly affected by increasing concentrations of cadmium, cobalt and lead when compared to controls. Specifically, germination percentage was reduced from 1 ppm to 100 ppm i.e. 77% to 46% with Cd, 64% to 50 % with Co and 78% to 70 % with Pb treatments. This data indicates that each heavy metal has its own impact on black gram seed germination. Similarly, shoot and root lengths were also reduced upon these heavy metal treatments. Although the percentage of germination decreased drastically (36% at 100 ppm) along with the increasing concentration of chromium, the root and shoot lengths were suddenly increased (hugely root length) when compared to controls. In conclusion, each heavy metal has its own critical point for each seedling or plant growth.

“…The induction of distributed phases confirming the suggestion that the effect of plant extract studied was on the mitotic spindle. The plant extract may suppress the spindle formation by interfering with tubulin and lowering the polymerization of microtubular subunits forming the spindle apparatus, thus chromosomes lose their ability to continue from metaphase stage to anaphase and telophase stage, Pickett-Heaps et al, (1982) and Mukherjee et al, (1990).…”

Mesembryanthemum nodiflorum L. (Aizoaceae) has long been used as food and in traditional medicine. This study was intended to explore the active groups within M. nodiflorum ethanolic extract and to study the cytological effects of M. nodiflorum water extract on Allium cepa L. root tips. Phytochemical analysis of M. nodiflorum ethanolic extract indicated the presence of alkaloids and triterpenes. Tannins, flavonoids and saponins did not found in M. nodiflorum alcoholic extract. Mitotic indices and distribution of cells in mitotic phases of A. cepa root tips were clearly changed after treatment with three different concentration of M. nodiflorum water extract (0.1, 1 and 3%) for 3h, 6h, and 12h. The maximum value of mitotic index 2.68% was observed after treatment with 3% for 6h, while the minimum value 1.35% was scored after 12h exposure to the same concentration. Different types of chromosomal aberrations were noticed. The present study revealed that M. nodiflorum water extract has a potent inhibitory effect on the mitotic activity of A. cepa root tip cells.
